I have a LG Nexus 5 and some time ago I had an issue with the headphone jack and it stopped working correctly. The phone "thought" that there was a headset plugged in when it wasn't, so I couldn't get any calls (the mic was shut off) and I couldn't play any media because the speaker was off as well.

I installed soundabout (and the PRO version) so I could get those features back. With the previous version and running on 4.4.4 everything worked flawlessly. But then I waited to the new version (2.5.8.1) so I could upgrade to Lollipop 5.0 and keep using soundabout.

Well, after installing both, the built-in mic isn't working. I turned off the "Wired Headset detection" and rebooted my phone. Now the media is going through the speaker (as expected) but the mic won't work. I cannot use the Google Voice Search or anything that requires the mic. Suggestions?

Alright, gave that a shot. This tablet thinks the headphones are always plugged in even when there's nothing there, so without soundabout neither the microphone nor the speakers work with Google Voice Search. Maybe someone with a working device could test?

I gave it a shot as well with my Nexus 5. Cleared cache, data, uninstall and reboot. Still recognizes the headphones even when they're not plugged in, so neither speakers nor mic are working, even for the Google voice search. There must be something different in the way Android deals with the microphone on Lollipop, apart from the "OK Google" detection/Voice Search. I rolled back to kitkat because it works just fine in there.

The first time I installed the new beta (.2) over the old Lollipop beta, and without restarting, like magic the microphone started working! However, after a couple minutes, all audio (microphone and speaker) cut out. Restarts and clean install did not bring back the audio, I reverted to the old beta. Clearly, its doing something right.

Only 2.5.8.1 and above worked in Lollipop. 2.5.8.1 is able to toggle the speakers, but not the microphone. When I upgraded to 2.5.8.1.2, microphone toggle worked briefly, but shortly after both microphone and speakers stopped working.

I tried the new beta version and the mic didn't work!I tried to clear all caches, data and remove the App (not the pro key app) and reboot and still didn't work!!Should I update my Nexus 4 to 5.0.1, or this may cause more problems?
